OK, explaination:
In toolshop is a workaround to give solid individual colors connected to material or function. Machined faces of this body have individual colors(RGB) and attributes connected to manufacturing. Coloring and attributes is managed with a grip, now , while solids created ( not only a one way process) the colors get lost but the attributes stay at the faces in most cases. For control it would be nice to select a solid, get all faces of the body recolor from face attributes. I haven't found a solution in grip cover this process, yet, at the time there is a second selection needed for ( Masking) the faces in grip. I hope its clear now.
